LUBRICATING DEVICE.

i Application filed December 19, 1904. Serial No. 237.535.

' To all whom it may concern:

ticularly to be used and which shall avoid Beit known that I, RUSSEL G. WOODWARD, a citizen -of the United States, residing at aukegan, in the county of Lake, State of Illinois, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a description, reference being had to the accom anying drawings, and to the letters and irgures of reference marked thereon.

y invention relates to an improvement in ricating devices, and as herein shown it is adapted for connecting-rods designed parto transmit motion from an eccentric to a part at the Opposite end of said connection-rod, oscillate. Heretofore a device of this character has been'proposed which was adapted for the reception of lubricant-absorbing material; but thishas'been found objectionable in practice, and it is the object of the present invention to provide asimple and effective de- .vice which shall freely supply oil to the .part to belubricated and which shall allow for the escape ofair while the reservoir is being filled,

danger of leakage.

The invention therefore consists in the matters hereinafter described, and referred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which` '.Figure 1 represents a face view of a connecting-rod embodying my invention, and Fig. 2 is a sectional view of the same, and Fi 3 is a section on line 3 3 of Fig. 2.

n the drawings, A represents the shell, which is adapted to embrace the ball-eccentric on a driving-shaft. It is provided with an openin a, leading into the socket B in the shank b o the shell, the socket B having its inner wall screw-threaded to receive the screw-threaded lower end ofthe intermediate member C, which screw-threaded lower end is also embraced by a am-nut c, by which the intermediate member may be set at any adjustment desired. At the upper end the intermediate member C is similarly screwthreaded and iits into a socket D on the upper shell E, which shell embraces a ball-stud or other member to be driven or to be connected to a member. to be driven. A jam-nut d is provided also in the upper portion'of this intermediate member.

which 'it is desired tok The intermediate'member or connectin rod C is hollow, as shown, and is formed wit 1 openings 1,2 for the entrance of lubricant and escape of air and has a cup-shaped portion 3, forming a reservoir externally screw-threaded, as at 4, and above the same a ange or yshoulder 5 to form a seat for the screwthreaded nut or casing 6, which screws down upon the cup and prevents the escape of the oil to the exterior of the connecting-rod. The reservoir 3 is of great convenience in oiling. The position of the cylindrical tube will vary slightly according to the length of the threads cut into the top or bottom part ofthe connection and upon the tube. This varying position will perhaps throw the holes into position inaccessible to the oil-can spout. `In this event the chamber 3 acts as a reservoir, and when the oil is put therein it will flow through the hole or holes into the tube. The holes preferably extend above the top ofthe reservoir 3 to allow the escape of air, even should the reservoir be filled. It will be understood that one openinl only might be used. By this arrangement the oil is prevented from overowing or working upwardly in the reciprocation of the connecting-rod, the only escape for such lubricant being through the lower end 'of the connecting-rod onto the part to be lubricated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l The herein-described device for connecting a drivin member to the part to be driven, inclu ing a hollow connecting-rod, forming a reservoir for the reception of the lubricant, with means to allow the outflow of the lubricant to the part to be lubricated,

there being an opening in said reservoir to allow the lubricant to be inserted, and means f independent of said reservoir for inlet-opening after the lubricant serted substantially as described.

2. The herein-described device for connecting a drivin member to a part to be driven, including a Iiollow connecting-rod forming a closing said reservoir for the reception of a lubricant, with means to allow theoutiow of the lubricant to the part to be lubricated, there being openings Into said reservoir to allow lubricant to be Inserted, a cup surrounding the reservoir adjacent said openings, and a cap fitting said 9s has been m- 'adjacent said openings, there cup and surrounding the reservoir for closing the inletopenings; substantially as de scribed.

3. The herein-described device for connecting a drivin member to a part to be driven, including a ollow connecting-rod forming a reservoir for the reception of a lubricant, with means to allow the outflow of the lubricant to the part to be lubricated, there being openings in'to said reservoir to allow lubricant to be inserted, a cup surroundin the reservoir gbeing a shoul der above the cup,'and a' cap screw-threaded on said cup, and seated on the shoulder when in closed position; substantially as described.

4. In a lubricating device, a hollow connecting-rod forming a receptacle for the lubricant and having .an outflow for the lubricant to the part to be lubricated, there being openings'into said receptacle to allow lubricant to be inserted, a reservoir surrounding said receptacle and having a screw-cap for closing said reservoir; substantially as def scribed.

5. In a lubricating device, a receptacle for the lubricanthaving an outflow for the lubricant to the part to be lubricated, there being openings into said receptacle to allow lubricant to be-inserted, a reservoir surrounding said receptacle, said inlet-openings extending above the top-of the reservoir toallow the escape ofair from the receptacle when inserting oil therein; substantially yas described.

6. In a lubricating device, a hollow con-v necting-rod forming a cylindrical receptacle for the lubricant and having an outilow for the lubricant to the part to be lubricated, there being an opening into said cylindrical receptacle to allow lubricant to be inserted, a` lreservoir surrounding said cylindrical receptacle and coverin the opening into said cylindrical receptac e, and a cover. for said reservoir to prevent escape of lubricant; substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

RUSSEL G. WOODWARD.
